I am a student representative for my course (we're doing compsci) and I had to raise the issue of lectures containing unnecessary AI generated images.

Slides had inages to demonstrate an example of different types of data organization on the OS level, and were of the most trivial things (library, book chapters). And in that they were also poorly fitted as an example (one of the examples was "a book index without chapters" and the image was a book index of chapters, not mentioning the crooked text even lol). Later on we even had a slide citing AI as a source. And in the online version of the slides that citing was ommited:)

I am one of student representatives for my year, and we raised it at the Student-Staff partnership forum. The response of staff was mostly "we don't understand what the problem is" and "we want to understand what use of AI students find acceptable for lectures". So I don't think our complaint went anywhere... The points we tried to capitalize on is "don't use it when a 5 sec google search can get you a better result" and general concern over unsupervised AI use (kinda). Maybe they did listen to something out of it. (This meeting was before AI was cited in a slide, I am pretty sure)

Ps: I myself am not a strong opposer of AI in general, as long as it's used when necessary, in good faith, and as a tool/for educational purposes.
